Abstract
PURPOSE: To reduce torque ripple at the time of light load and also to enable torque to become generated immediately even at the time when load became heavier, by changing voltage to be impressed on an induction motor in accordance with magnitude of slip.
CONSTITUTION: A defference between a speed command signal put into an input terminal A and a revolving speed signal from a speedometer generator 5 is removed at a summing point, and the difference is amplified by an error amplifier 9. An output from this error amplifier 9 is a slip of an induction motor 4. A signal from a summing point 31 increases as the slip increases, and it decreases as the slip decreases. Power transistors Q1 through Q6, which compose an inverter circuit 3, are controlled by being turned on and off in accordance with this output, so that the voltage to be impressed on the induction motor can be changed.
